SPECIFICATION forming part of Letters Patent No. 234,963, dated November30, 1880,

Application filed April 22, 1880. (No model.)

To all whom it may concern:

Beit known that I, CHARLES COGGSWELL, of Dodge Centre, in the county ofDodge and State of Minnesota, have invented a new and valuableImprovement in Bob or Draft Sleds; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionandoperation of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters and figures ofreference marked thereon.

Figure 1 of the drawings is a representation of a top view of myimproved sled. Fig. 2 is a longitudinal section thereof. Fig. 3 is asectional detail, and Figs. at and 5 are details.

This invention has relation to bob or draft sleds or sleighs; and itconsists in the construction and novel arrangement of the beveledforward and backward sloping cross beams, the inclined knees between therunner and cross-beam and connected thereto by end tenons, and thedetachable tie-rods extending through the runner and rave, and thesecuring-nuts on the ends of said rods above the rave, as hereinaftershown and described.

In the accompanying drawings, the letter A designates the runners; B,theinclined crossbeams; G O, the knees, which slope, respectively,forward and backward, as shown, having similar inclination to that ofthe crossbeams; and D, the raves or side timbers of the sled. The kneesG O are designed to afford the necessary support from the runner to thecross-beam, and the sides of the latter also slope forward and backwardin line with the sloping faces of the knees. The upper surfaces of thecross-beams are beveled to receive inclined outward and downwardlaterally on each side, it is apparent that their position is such as toafiord a strong bracing support against rearward, forward, or lateralstrain.

the heads or hooks at the lower ends of said rods, along the front andrear faces of each knee and cross-beam through the rave, and are drawnforcibly upward and secured by the nuts 0, which work on the threadedportions 0 against the uppertsurt'ace of the rave. Usually the front andrear faces of the knees and cross-beams are recessed or grooved, asindicated at f, to receive the tie-rods, which are designed to lie inclose contact with said parts and serve an important purpose as sidebraces to the sled.

This construction enables the sled to be readily taken apart forrepairs, when the nuts 0 are unscrewed from the tie-rods, and therepairing can be done by the blacksmith or farmer without the necessityof having re course to a mechanic especially skilled in the constructionof sleds. Economy in the cost of construction is also an importantobject of this invention.

What I claim, and desire to secure by Letters Patent, is-

In a sleigh-runner, the combination, with the runner and rave, of theforwardly and backwardly sloping knees C 0, having end tenons, z, andthe beveled cross-beams B, hav-
